SPECIFICATION forming part of Letters Patent No. 565,221, dated August 4, 1896.

Application iiled December 9, 1895. Serial No. 571,523. (No model.)

T0 ctZZ whom t may concern:

Be it known that 1, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Weighing-Machines, of which the following is a specification.

This invention relates to weighingmachines, the object being to provide an improved organization of valve and valve-actuating mechanisms particularly adapted for use in connection with weighing-machines for weighing sluggish, lumpy, and other similar materials.

In the drawings accompanying and forming part of this specification, Figure 1 is an end elevation of a weighing-machine embodying my present improvements as seen from the left in Fig. 2, the valves being in a position to permit the iiow of the full supplystream into the bucket of the machine and the bucket-closer being illustrated closed. Fig. 2 is a rear elevation of the machine. Fig. 3 is an enlarged end elevation of the upper part of the machine as seen from the left in Fig. 2, the valves being in a position corresponding with Fig. 1. Fig. et is an enlarged end elevation of the upper part of the machine as seen from the right in Fig. 2, the valves being in a position corresponding, respectively, with Figs. 1 and 2. Figs. 5 and (5 are views similar to Fig. 3 and show two successive positions of the valves. Fig. 7 is a plan view of the left-hand portion of the machine. Fig. Sis a rear elevation of the upper and left-hand ends of the machine. Figs. 9, 10, and 11 are detail views of the valves and certain adjacent parts of the machine, the valves being illustrated in crosssection and in three successive positions.

Similar characters designate like parts in all the iigures of the drawings.

For convenience in illustrating the purpose and nature of my present improvements, these are shown embodied in a weighing-machine constructed in accordance with several Let-- ters Patent granted to me, certain of which will be hereinafter specifically referred to by date and number, and said machine will be briefly described in connection with said improvements.

The framework for carrying the operative parts of the machine may be of any suitable construction, and is shown in the drawings comprising two side frames or uprights 2 and 4, which are mounted upon a chambered supporting-base 3 and connected by a top plate 5, and the latter is illustrated carrying a supply-chute H, which is adapted for containing the mass of material to be weighed.

The discharge-chute of an elevator apparatus is shown at D, delivering the material in the form of a stream to the supply-chute H, from whence it is directed to the bucket of the machine.

The base 3 is shown carrying suitable beamsupports-such as the V-shaped bearings 2O and 20'--for supporting the beam mechanism which supports the bucket mechanism, consisting of the bucket and its operative devices.

As a means for supporting the bucket or load-carryin g receptacle, which is designated in a general Way by G, a pair of oppositelydisposed counterweighted scale-beams are shown at B and B', respectively, pivotally mounted on the beam-supports 2O and 20-as, for instance, by means of the pivots or knifeedges 24 and 211. The scale-beams B and B', intermediate of said beam-supports, are illustrated carrying the bucket-supporting knifeedges 15 and 17, and the bucket G is shown carrying on each end thereof the hangers 555, which latter carry the V-shaped bearings 16, which are adapted to be pivotally supported by the pivots or knife-edges 15 and 17, carried by the beam mechanism.

The machine will have the usual poising and counterpoising mechanisms, all that part of the beam mechanism intermediate of the beam-supports, including the bucket mechanism, constituting the poising mechanism and all that part of the beam mechanism located outside of said beam-supports constituting the counterpoising mechanism.

The bucket mechanism will have alternate ascending and descending movements with the beam mechanism, for the purpose of receiving and discharging bucket-loads. and is shown consisting of two members, one of which is shiftable relatively to the other for discharging the bucket-load. The bucketcloserL, which controls the discharge of the bucket-load, is shown constituting the shift- IOO able member of the bucket mechanism, and is shown pivoted at 77, adjacent to one side of the discharge-opening of the bucket, and as having formed, preferably integral therewith, the eounterweighted arm 79, which tends to return the bucket-closer to its closed position.

As a means for supporting the bucket-closer L, an inverted toggle is shown in the drawings operatively connecting the bucket-closer L with the bucket G. (See dotted lin es, Fig. l, and partially illustrated by the full lines in detail views, Figs. 3, 4, 5, and 6.) In the form shown this toggle comprises a rocker 550, pivoted adjacent to the upper rearward side of the bucket, the pivot being shown at 550", and a long connecting-rod 596, pivoted to said rocker and also to the closer in such a manner that when the closer is shut the two pivots of said connecting-rod or toggle member 596 will be nearly in line with, and the upper of said pivots will be above, the rocker-pivot, whereby when the rocker is engaged by the bucket-closer latch and held in that position the closer will be supported with a minimum pressure on the latch, as practically all of the weight of the bucket contents will be carried on the pivot 550 of the rocker.

The closer-latch for locking the rocker in position when the closer is shut, and which is designated by 82, is shown herein pivoted on one end of the bucket G (see dotted lines, Fig. l) and having a detent in position for engaging a cooperating detent carried by the rocker. In the form shown the closer-latch S2 swings upward to engage the detent on the rocker 550, and is released from engagement therewith by a downward movement or pressure thereon.

In weighing free running materials in weighing-machines the valve which controls the 'llow of the supply-stream into the bucket is simply opened, when the material will gravitate into the bucket.

In weighing sluggish and lumpy materials considerable dificulty is encountered, owing to the inherent tendency of such materials to block and clog at the stream-controlling point, rendering it impossible to obtain a satisfactory drip-stream, which is a very important factor. To overcome these and other difficulties, I have devised several different forms of feeders, which feed or force the material to be weighed in a stream from the supplychute and direct it into the bucket of the machine.

The form of feeder shown in the accompanying drawings, and which is designated by F, is substantially similar to the feeder disclosed and claimed in a concurrently-pendin g application filed by me November 21, 1805 Serial No. 569,627. The feeder shown in said application has a feeding movement of variable efiiciency. Commencing with each operation of the machine said feeder will have a relatively rapid or accelerated movement,

which is progressively decreased as the bucket descends, the result being at first the forcing or feeding into the bucket of a stream of relatively large volume, which is progressively diminished as the bucket descends. On the completion of the bucketload the feeder movement will be stopped, the consequence being a stoppage of the fed or forced stream. Any suitable means for seeuringthis variable movement of the feeder may be employed.

The supply-chute ll is illustrated carrying bearings 30 and 30 and 3l and 3l', in which a-re shown journaled, for rotative movement, the shafts 32' and 33/ of the rolls 32 and 33, which are connected by a belt 3l, underlying the supply-chute and preferably in close relation therewith. The rolls and 33 and connecting-belt 34, which may be of canvas, leather, or other suitable material, constitute the feeder. The direction of movement oli' the belt 3l is indicated by the arrow in Fig. 1, and on the movement of the belt 3l in the direction indicated a stream of material will be fed or forced from the supply-chute Il through the supply orifice or opening 3l" and into the bucket G. The shaft 33/ of the roll is shown extending beyond the frame of the machine, and this shaft maybe operated by any suitable speed-modifying apparatus, as above set forth. On the stoppage of the feeder, which is at the close of the poising period-that is, on the completion of the bucket-load--there will remain on the feeder, between the supply-chute and the outer edge of the former, a relatively small quantity of the mass, which, in practice, is projected into the already-loaded bucket, the consequence being an overloading of the machine. For catching this last part of the supply-stream, orwhat is termed the drizzle 7 or spray, my invention contemplates the employment of a drizzle-catcher, which is supported by a suitable carrier and which is normally located away from the line of How of the supplystream, but which is, at the proper point in the operation of the machine, by proper mechanism, so projected as to intersect the line of flow of the supply-stream, thereby catching the drizzle or spray mentioned and preventing its flow into the bucket.

The drizzle-catcher carrier is designated by 70.

The top plate 5 of the machine is shown carrying the projecting arms 5, between which is illustrated, piveted for oscillatory movement, the balance-weight 90 of the carrier 70, and said balance-weight 90 is shown carrying the hangers 90, which latter support the carrier 70, these parts being' preferably formed integral, the balance-weight 00 tending normally to maintain said carrier in a vertical position, as indicated lin Fig. t), so that the same will have no tendency in itself to move in either direction.

It will be observed that the pivot or center of motion 70 ofthe carrier is located rela- IOO IIO

tively remote from the supply-chute, so that the same will be thereby normally held away or at some distance from the supply-stream.

The drizzle-catcher is shown at 60, and is in the nature of a valve, and will be shiftably supported by the carrier for a purpose to be hereinafter described. The carrier '70 is illustrated carrying on the end walls thereof the bearings 71 and 71', (shown most clearly in Fig 2,) in which are shown journaled the laterally-extending arms 60 and 60", carried by the drizzle catcher or valve 60, the latter of said arms being extended for some distance and shown also as journaled in the cam 500.

As a means for moving the carrier 70 toward the supply-stream, also termed the closing movement thereof, I prefer to employ mechanism substantially similar to that disclosed in Letters Patent No. 548,843, granted to me October 29, 1895, to which reference may be had for a more particular description thereof, and which will now be briefly described. A depending cam is shown at 500, operative with the carrier 70, being illustrated as carried by the balance-weight 90. The cam 500 is illustrated having formed thereon the connected cam-faces 501 and 502, the latter being of relatively greater power or efficiency than the former, which cam-faces are in position to be engaged by an actuator 504. This actuator is shown as a counterweighted lever pivoted at 504' to the side frame 4 and having the weight 507 thereon forward of the pivot thereof, said weight being preferably adjustable along said lever to adapt the same to varying conditions. The lever 504, to the rear of the pivot thereof, is shown carrying an antifriction-roll 506, adapted to engage one or the other of the camfaces 501 and 502 of the cam 500.

During the first part of each operation of the machine the antifriction-roll will ride along the cam-face 501, thereby moving the carrier 70 slowly toward the supply-stream. At the close of the poising period the roll 506 will be at about the intersection of the camfaces 501 and 502, the carrier 70 being held against further movement at this time to permitthe liow of the drip-stream into the bucket G. At the close of the poising period the carrier 70 will be released and the antifrictionroll 506, leaving the cam-face 501, will engage the cam-face 502 of relatively greater efficiency, thereby quickly projecting said carrier toward the line of iiow of the supplystream.

It will be remembered that my present improvements embody, in part, a carrier and a drizzle-catcher, which is shiftably supported thereby. The drizzle-catcher 60, which is shown concaved, is normally located out of line' with and below the carrier 70, but at the close of the poising periodthat is to say, when the feeder has been stopped on the completion of the bucketloadthe former will be quickly shifted relatively to the carrier' 7 0 for the purpose of catching the drizzle or spray from the feeder and for preventing its entrance into the bucket G.

As a means for shifting the drizzle-catcher relatively to the carrier 70, a toggle or toggle connection, independent of the latter, will connect the former with some part of the machine, (herein illustrated as a fixed part thereof,) so that when the carrier is shifted the drizzle-catcher 60 will have a shifting movement relatively thereto. It will be remembered that one of the supports of the said drizzle-catcher has been described as an extended arm 60", said arm 60 being j ournaled in the cam 500. The arm 60 is illustrated carrying at a suitable point thereon the crankarm 61, which constitutes one member of a toggle. The other member of the toggle is shown as the connecting-link 62, which is pivotally connected with the arm 61 at 61 and at 62H with the projection 63, carried by the side frame 4 of the machine. During the reducing period (see Fig. 3) the antifrictionroll 506 of the actuating-lever 504 will be in engagement with the cam-face 501, and it will be observed on reference to said figure that at this point the toggle-pivot 61 is located above the toggle-pivots 60" and 62".

As the carrier 70 closes or moves toward the line of fiow of the supply-stream the drizzle-catcher valve 60 is of course carried therewith. During the reducing period the volume of the supply-stream will be progressively decreased as the speed of the feeder is likewise reduced, and the drizzle catcher or valve 60 will be located transversely of and below the carrier 70. As hereinbefore stated, both of said members will be located away from the line of iiow of the supply-stream, to thereby permit the vertical descent of said stream without obstruction into the bucket. As the carrier 70 moves toward the supplystream, the drizzle-catcher 60 will have a slow shifting upward movement relatively thereto, due to the resistance of the toggle member 62, which is in the nature of an actuator independent of the actuating mechanism for the carrier 70, and, as hereinbefore stated, is pivotally supported by a fixed part of the machine. This slow movement is imparted by the actuator 504, the antifriction-roll 506 of which is on the cam-face 501 of the cam 500. At the commencement of the poising period (see Fig. 5) the roll 506 will be at the intersection of the two cam-faces of the cam 500, and though the two members '70 and 60 have not yet intersected the line of flow of the supply-stream the latter is then relatively reducedbeing in the form of a dri p-streamand is relatively adjacent to but not in contact with said stream. This drip-stream will iiow into the bucket for a short period of time for the purpose of completing the bucketload. On the completion of the bucket-load the bucketwill descend below the poising-line, this action releasing the carrier 70. When the said carrier 70 is released, the actuator 504, through the roll 506, leaving the cam-face IOO IIO

501 and engaging the cam-face 502, quickly closes the same and simultaneously therewith the drizzle catcher or valve G0 is projected upwardly by the actuator or toggle member G2, this action throwing the togglepivots 61', and 02" approximately into line. (See Fig. G.) On the projection of the drizzle catcher or valve G0 in the manner indicated said drizzle-catcher valve catches the drizzle or spray which drops from the feeder succeeding the stoppage thereof.

In weighing coal it sometimes happens that several lumps drop into the drizzle-catcher 00. In such event these will be directed away from the discharge edge thereof, and by the latter into the carrier 70. On the other hand, if the machine is weighing materials of a finer nature, but more sluggish than coal, the spray is caught by the valve G0 and directed toward the carrier 70, the latter acting in the nature of a scatter-guard, and being provided with a transverse wall 70 to further prevent the entrance of the spray or drizzle into the bucket G.

To prevent wasting and scattering of the material, a scatter-guard is provided, and such a guard is shown at obliquely disposed relatively to the bucket and carried by the front wall thereof, being secured thereto in some suitable manner. This guard G5 is also shown projecting a slight distance beyond the feeder, so that if any of the material falls from the feeder it will drop on said guard and therefrom into the bucket on the mass already therein.

As a means for actuating the carrier to move the same away from the line of ilow of the supply-stream l prefer to employ valveactuating mechanism substantially similar to that disclosed in Letters Patent No. 548,839, granted to me October 29, 1805, to which reference may be had, and which will now be described.

The carrier 70, which is also in the nature of a valve, is shown having a connecting-red 558 pivotally secured to the upper rearward portion thereof, and having the lower end of said rod in position to be engaged by an actuator, which will now be described, said connecting-rod 558 being also shown having a pivotal connection by means of a guide-link 559 with a relatively-fixed portion of the machine.

The scale-beam B is illustrated carrying a counterpoised lever 551, pivoted at 551 between the bucket-suliports. (See dotted lines, Fig. 1, and full lines, Fig. 2.) This counterpoised lever exerts its force on the counterpoising mechanism, being held in its normal position by the stop 551 engaging the beam B. This counterpoised lever 551 is adapted,

at a predetermined point in the operation of the machine, to have the effective force transferred from the counterpoising to the poising mechanism of the machine, and is also adapted, on the return stroke thereof, for engaging the connecting-rod 558, to thereby impart an upward thrust to the same, whereby the carrier 7 0 and thereby the drizzle-catcher or valve (50 will be moved away from the line of flow of the supply-stream to again permit the nnobstructed flow of the same into the bucket. Hence it will be evident that for actuating these members to open the same a two-stroke actuator is provided, which is effective on. one of said strokes for actuating the same. Ou the return stroke of t-he shiftable member 551 an upward thrust is imparted to the connecting-rod 558, and these members GO and 70 will thereby be moved away from the line of liow of the supply-stream. As the carrier 0 is thus moved the valve 00, which is in line therewith when these are closed, will also be carried therewith. On the iirst movement of the carrier 70 the toggle-pivots G1, 00, and G2" are thrown out of line to the position indicated in Fig. 5, and on the continued movement of the carrier the toggle member 02, serving as a valve-actuator and acting as a fixed resistant, tends to rock the crank-arm or toggle member 61, thereby shifting or moving the drizzle-catcher valve GO out of line with the carrier 70, this action continuing until the latter is in its normal position, as indicated in Fig. 3.

At a predetermined point in the closing movement of the carrier 70 or at the commencement of the poising period the roll 50G of the lever 50-1 will be at the intersection of the cam-faces 501 and 502. At this point the carrier 70 and valve 60 will be held against further movement to permit the unobstructed flow of the drip-stream into the bucket for the purpose of completing the bucket-load therein. A stop-arm is illustrated at 509, carried by the carrier 70. This stop-arm 500, which is oscillatory with said carrier 70, is in position. to be engaged by a cooperating stop carried by the poising mechanism. (Herein illustrated as the bucket-hanger The coperating stop for this purpose is shown as a by-pass stop, supported for oscillatory movement, a suitable stop being employed for maintaining the same in operative position. The length of the vertical arm of the by-pass 570 is such, relative to the stop-arm 50H, that the former will, at the commencement of the poising period, engage said stop-arm 500, and at the close thereof, due to the descent of the bucket below the poising line, said stop-arm 500 will be released, this action also releasing the carrier 70, whereby the latter may be moved toward the line of flow of the supplystream. On the return stroke of the stop-arm 509 this will engage the vertical arm of the by-pass 570 and oscillate the by-pass about its pivot, and will be thereby permitted to resume its normal position, as indicated in Fig. 1. Then the stop-arm 500 has passed said by-pass 570, the latter, being counterweighted, will drop to its normal posit-ion.

As a means for releasing the shiftable member of the bucket mechanism, which has been hereinbefore described as the bucket-closer IOO TIO

L, I prefer to employ an actuator or releaser device operative by the --power of the moving carrier ',70.

It will be remembered that a latch 82 has been described as normally holding ythe bucket-closer L against opening movement by engaging the toggle member 550 of the bucket-supporting means, and it will also be remembered that said latch hasV been described as having a downward movement for disengaging the same from said toggle member. Fig. 1, and full lines, Fig. 2) provided at the rear of the pivot thereof with a stop-pin 82', the purpose of which will now be described.

It will be remembered that the carrier 7 0 has been described as carrying a long connecting-rod 558. This connecting-rod is shown provided at a proper point thereon with a latch actuator or releaser device 88. The connecting-rod 558 on the closing movement of the carrier 70 will have a descending movement therefrom. At the commencement of the poising period the carrier 7 0 will be held against further movement in the manner hereinbefore described. When said carrier 70 is so held, the releaser device 8S will be adjacent to the stop-pin S2', carried by the latch 82. lVhen said carrier has been released and is closing, the releaser device S8 will be projected downward into contact with the stop-pin S2', thereby depressing the latch S2 and disengaging the same from the toggle member 550, at which time the bucket-closer L will be free of all restraint, and the mass of material in the bucket pressing against the same will open the latter for discharging the bucket-load.

The operation of a weighing-machine embodying my present improvements, briefly described, is as follows: With the parts in their normal positions, as indicated in Figs. 1, 2, 3, and 9, the carrier 70 and drizzlecatcher 60 are located at some distance away from the supply-stream, to thereby permit the unobstructed ow of the same into the bucket G. Vhen a certain proportion of the bucket-load has been received by the bucket, this tends to descend, the beam mechanism, of course, descending therewith, the shiftable member 551 thereon also falling slowly from under the connecting-rod S, permitting a slow-closing movement of the carrier 70 and the supported drizzle-catcher 60 by the actuator 504, engaging and riding over the cam-face 501 of the valve-closing cam 500. During this period of the operation of the machine the volume of the supply-stream is being gradually reduced by the slackening in speed of the feeder. At the commencement of the poising period the supply-stream will have been materially reduced, but the members and 70 will not be in contact therewith. At this point in the operation of the machine the antifriction-roll 506 of the lever 504 will be at the intersection of the cam-faces 501 and 502 of the cam 500, and

Said latch is shown Y(see dotted lines,

the carrier 7 07 and thereby the drizzle-catcher 60, will be held against further movement by the engagement of the by-pass stop 570 with the stop-arm 569, which is operative with said carrier 70. The drip or reduced stream will then flow unhindered into the bucket for the purpose of completing the bucketload therein. On the completion of the bucket-load the bucket will descend below the poising-line, this action releasing the stoparm 569 and thereby the valve-carrier '7 0. When the latter is released, the roll 506 of the valve-closing lever 504, leaving the camface 501, will engage the cam-face 502 with relatively greater efficiency, thereby projecting the carrier in a forward direction; and during this operation the drizzle-catcher 60 will be shifted relatively to the carrier 70 and into line therewith by the straightening of the toggle members (51 and 62, so that said drizzle catcher or valve 00 may catch the drizzle or drip from the feeder F on the vstoppage thereof, thereby preventing the same from dropping into thel loaded bucket. On the closing movement of the carrier 70 the connecting-rod, and also the actuator 88, will have a descending movement therefrom. At the commencement of the poising period the actuator SS will be adjacent to the stop-pin 82@ carried by the latch 82. Vthen the carrier 70 is released, this actuator is thereby projected downwardly, and succeeding the catching of the drizzle by the drizzle catcher or valve 60 depresses said latch S2 and disengages the same from the toggle member 550, thereby freeing the closer L of all restraint. At this point in the operation of the machine the mass of material in the bucket, resting against the bucket-closer L, will force the same open for discharging the bucket-load.

Having thus described my invention, I claim- 1. The combination with a bucket and with a power-dri ven feeder for supplying a stream of material thereto, of a carrier; a drizzlecatcher shiftably supported by said carrier; mechanism for actuating the latter; and an independent, movably-supported device directly connected to said drizzle-catcher and to a fixed part of the machine for effecting a shifting movement of said drizzle-catcher.
